Hi,
I need to add Lattice Makers 2400 x 460mm Fence Extension Paling to our existing fence on a side and back.
These extensions seem to fit on uncapped fence. Is it possible to install these on a capped fence?
This is our back fence. Our side is Paling.

This is our side fence (Posts are on our side)

Another problem is, capping is not flat and is similar to this.Will i need to completely remove the capping?

Will weight of the extensions be an issue?
Thanks.
